Adafruit 16 Channel Servo Driver with Raspberry Pi
Servo motors are often driven using the PWM outputs available on most embedded MCUs. But while the Pi does have
native HW support for PWM, there is only one PWM channel available to users at GPIO18. That kind of limits your
options if you need to drive more than one servo or if you also want to dim an LED or do some sort of other PWM
goodness as well. Thankfully ... the PI does have HW I2C available, which we can use to communicate with a PWM
driver like the PCA9685, used on Adafruit's 16-channel 12-bit PWM/Servo Driver!

I cannot thank you enough, this video is the only reason I was able to actually make the board work! Keep up the good work!
Thanks, I stumbled upon the same issues and this made it super easy to go on
Recommended power supply is 5v 2A
Thank you so much. I´m from Brazil and your video saved me... Congratulations
Thank you, you helped me to solve the issue I was having :)
Having an issue with the servo driver. Everything is good until I add the fifth servo. Once I do, the black diode next to the capacitor burns up. Any thoughts?
Hello, thank you for this amazing tutorial. Quick question, does the servo driver need power when it is connected to Raspberry pi which already has power. i will only connect 3 motor to that.
Hi.. I have 8 servo Sg90. What power supply for these all servo (volt and ampere)?
Hello, Can you please explain me what are the second and the third parameters of pwm.set_pwm()
which software are you using for simulation
a previous video youve posted about potentiometers controllong leds in neopixel, the linked code does not work. if you please could fixs that it would be greatly appriciated.
have good day:)
16 channel means I can connect 16 servo motors to this motor driver. right?
Does this work whith stepper motors too??? Heve a nice day!
Hi, what power supply did you use for the motors? (Volt & Amp)
I have a 5V 4A power supply connected to the PCA9685. The most important part to match is the 5V, as the current (amperes) are drawn as needed.
Which power supply are you using?
Nice Explanation,Madam.Needs More.
I made it! thanks to you!!
Can I also control 16 12V DC motors ??
I am driving 18 servos for a hexapod robot project using two PCA9685 by chaining 2 of them. The problem I am facing is the jitter problem. I don't have the knowledge to solve it. Please help me
Hello, I have a little problem with your tutorial and know that I have an error when I run the simpletest.py program. The error is No module named Adafruit_PCA9685. PS I did exactly what you did -_-
do you have an idea i'm a taker
Will this work on a raspberry pi zero?
Can please someone give me the link for the Raspberry pi simulator that she uses in his video?
Can u add an esc too?!
А сколько максимум серво моторов можно подключить? И чтобы ими можно было управлять отдельно.
I get this error
runtimeerror : could not determine default i2c bus for platform
I have enabled i2c interface, how I solve this error?
What os is install on de rpi
Hi can Multitasking operation? Need free rtos?
Can i get multiple servo motor code for raspberry pi ?
I still can't find a video that works with my board, I have the 16-Channel Servo Driver HAT for Raspberry Pi (12-bit I2C) and if anyone can help me I would greatly appreciate it (I use python code, not the terminal)
how to control servo motor with keyboard righet und left, middle, with raspberry pi, do you know write cod
i have an error: module 'Adafruit_PCA9685' has no attribute 'PCA9685'. I don't know why. Can you have me fix this. Thank you so much
Doesnt work with python 3..?
It would be nice to see a tutorial how to control multiple mg995 over ethenet mqtt :)
Thank you you help me to slove issue
What do you use to power your motors?
External power 5v 2a
Good tutorial!!
after executing the command "python simpletest.py" I got the error "ImportError: No module named Adafruit_PCA9685". Any ideas?
use python 2.7.. dont use thonny
i have err: module 'Adafruit_PCA9685' has no attribute 'PCA9685'. plese told me how to fix them :((. Thank you somuch
How to connect raspberry with ssc from rtrobot?
which programm do u use?
Fritzing
I have a Raspberry Pi Zero and Phyton3 and I could not install:
sudo pip3 install adafruit-circuitpython-servokit
Can anyone help me, please?
What's the simulator u use this video?
Fritzing
Thanks!
Top parabéns
Hi sir, make multiple stepper use raspi pliss
Thank you. This video was very helpful! :)
Anyone Please help me find what software to design my projects on ? Like they use in the video to draw the pin connections. Thanks
Fritzing
@@denon9000cd Thanks, just got it and its great. now i can do it on the computer instead of scraps of paper ;-)
Nice
Could you help with ax-12a servo with arduino??
i feel bad for the 2nd servo being slapped by the 3rd one
Can we make a dog form this
Amazing video! God bless. Always remember Jesus Christ loves you!❤️🙏
El sueño de conoserte
While this is interesting, unfortunately running servos one at a time has no real applications, unless you only have one servo to control something very simple. Have you tried to run at least 2 of them simultaneously?
Cutie
I2c single bus addressing basically. You guys look it up. You'll thank me later
Tats not control.. Control means using keybod, joystick etc.. This is more of a demo.
What os is install on de rpi
